The body urged all countries to respect international law and offer assistance to everyone fleeing from the war irrespective of their race.

"Reports that Africans are singled out for unacceptable dissimilar treatment would be shockingly racist and in breach international law," AU said in a statement issued late Monday.

The union hailed member countries and their embassies in countries neighbouring Ukraine who are supporting those fleeing from the war.

Africans living in Ukraine had complained of racism at the Ukraine-Poland border.
